Earlier kissing scenes were not included in promos, but it has become a trend now.
When asked about the same, Karan Johar said: "It's great these kids of the new generation are kissing on screen. It's the new ethos... but senior actors didn't do this. I like to watch kissing scenes, it's wonderful. Kissing scenes help to get opening and people also like to see it, so it's all about kissing."
